2017 Map of Chandalar B-1 SE

About this map

East Fork Chandalar River dominates the southern reaches of this interior Alaskan quadrangle, cutting through a landscape defined by significant elevation changes. This 2017 survey by the U.S. Geological Survey illustrates the drainage patterns of the Yukon-Koyukuk region, where Crater Creek flows from the high northern ridges to join the larger river system below. The map's contour lines reveal the deep valleys and steep gradients typical of the Brooks Range foothills, providing a clear picture of the hydrological relationship between Crater Cr and the glacial-fed waterways of the north. The absence of roads or man-made structures highlights the true wilderness character of this area in the early 21st century.
